Gynecomastia is a benign condition characterized by an abnormal increase in the quantity of glandular tissue in one or both breasts. It manifests itself as a result of hormonal imbalances throughout puberty and later in life. Although gynecomastia is not a serious condition in most cases, individuals may experience embarrassment as a result of their circumstances. Depending on the underlying cause, some patients may heal spontaneously, while others may require medication or surgery. The intention of the case is to emphasize the mastopexy method as a mastectomy technique on a young adult patient who was diagnosed with idiopathic gynecomastia and had long-standing compliance. The technique is frequently performed in the oncoplastic surgical treatment of breast cancer. In our case, the cosmetic appearance was at an expected level, and the feared consequence of nipple-areola complex necrosis did not occur. In the treatment of gynecomastia, it is difficult to make a decision that will be beneficial for the patient, which requires a long-term examination process. Once the surgery is required as a treatment method, consideration should be given to the potential of recurrence following surgical treatment, as well as the scar formation of the chosen incision.Keywords: Gynecomastia, liposuction, male breast enlargement, mastectomy.
